Diagnosing a rash typically involves a detailed medical history and physical examination. Key questions include:
- When did the rash start? - Where did the rash first appear, and how has it spread? - Is the rash itchy or painful? - Are there any associated symptoms like fever, cough, or fatigue? - Have you been exposed to any known infectious agents, such as a person with measles or a tick bite?
Laboratory tests, such as blood tests, skin biopsies, or cultures, may be necessary for a definitive diagnosis.
